This problem seems quite similar to a problem another user had although it was with creating directories rather then moving them. They told me the issue got fixed after the "Microsoft .NET Framework 2.0 Service Pack 1" and the "Microsoft Visual C++ 2005 Service Pack 1 Redistributable" were installed which I'm not entirely sure why, although it might have to do with how the app was created, you should get the redists on Microsoft's website and see if that fixed the issue
